+ * Date:    12 December 2003
+ * SUMMARY: Testing regexps with unescaped braces
+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=228087
+ *
+ * Note: unbalanced, unescaped braces are not permitted by ECMA-262 Ed.3,
+ * but we decided to follow Perl and IE and allow this for compatibility.
+ *
+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=188206 and its testcase.
+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=223273 and its testcase.
